Teams error CAA70007

Hi,

One of our users keep getting an error message when opening teams, this is only happening to a single users, on their machine, unfortunately I am not able to check if it would work on other machine or if other users can work on their machine due to working from home. Basically it opens, asks them to login, when they login it doesn't ask for password it just goes straight to the error, and we can't get further, they are able to login to teams.microsoft.com, but the app wont work, I have tried the following steps:

Reinstalled the app

Rebooted the machine

Uninstalled the app, cleared the cache and then reinstalled the app

Closed the app and cleared the cache and then reopened the app

Removed the teams license from o365 admin portal, then re-added the teams license

is there anything else I can do to try to resolve this issue? 

Kind Regards,

Brendan

Hi,

Try to sign the user into Edge - and enable SYNC.

That fixed it for us!

Same here. Teams doesn't work, and Edge shows this error code.

Same here. Teams doesn't work, and Edge shows this error code.

I was able to correct this by changing my proxy settings.

In Windows, go to Proxy Settings and change Automatically Detect Settings to OFF if you are not using a proxy.

If you are using a proxy, ensure that the proxy settings are correct.

Everything immediately began working correctly once I did this.

Hope my experience helps you.

Thanks, but it didn't help.

Solved by running in compatibility mode. See this thread.
